Abstract: The overall system performance is of interest when multitasking concepts are used in a multiprogramming environment. To get reliable results, a programming system is developed, generating synthetic user programs on a CRAY multiprocessor which simulate a given work load in a flexible way by using the hardware performance monitor (HPM). The resulting benchmark environment is used to insert additional sequential as well as parallel programs. First results obtained from these investigations seem to prove the efficiency especially for the fine-grain multitasking concepts which provide good performance in dedicated as well as batch oriented multiprogramming environments; for selected production codes on the CRAY Y-MP these concepts now are used to evaluate their effects on a loaded system.
